The anterior ramus of a typical spinal nerve innervates the anterior and lateral trunk and the limbs.

Explanation:

The spinal nerves originate from the spinal cord. Each spinal nerve is made up of two roots from the spinal cord, a posterior sensitive one where the spinal ganglion is located and another anterior or motor one, respectively, to the posterior lateral and anterior lateral grooves of the medulla through the root filaments. On its way, the spinal nerve emits four branches (meningeal, communicating, posterior and anterior). The anterior ramus supply the muscles and skin of the rest of the trunk and limbs. The anterior ramus of the thoracic spinal nerves remain independent, retain the segmental structure of this region of the body, and constitute the intercostal nerves.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
